Francis Liu commented on HBASE-20704:
-------------------------------------
Failing tests passed locally doesn't seem related. Committed to master,
branch-2, branch-2.1 and branch-2.0. Need a slightly simpler patch for 1.x
> Sometimes some compacted storefiles are not archived on region close

> During region close compacted files which have not yet been archived by the
> discharger are archived as part of the region closing process. It is
> important that these files are wholly archived to insure data consistency. ie
> a storefile containing delete tombstones can be archived while older
> storefiles containing cells that were supposed to be deleted are left
> unarchived thereby undeleting those cells.
> On region close a compacted storefile is skipped from archiving if it has
> read references (ie open scanners). This behavior is correct for when the
> discharger chore runs but on region close consistency is of course more
> important so we should add a special case to ignore any references on the
> storefile and go ahead and archive it.
> Attached patch contains a unit test that reproduces the problem and the
> proposed fix.
